After servicing brakes and before moving motorcycle, pump brakes to build brake system pressure. Insufficient pressure can adversely affect brake performance, which could result in death or serious injury. (00279a) After servicing the brake system, test brakes at low speed. If brakes are not operating properly, testing at high speeds can cause loss of control, which could result in death or serious injury. (00289a) Maintenance and Cleaning Chrome parts must be maintained regularly to ensure that they keep their original shine and luster. 1. Clean heavily-soiled wheel surfaces using Harley Wheel and Tire Cleaner, part number 94658-98, applied with Harley Wheel and Spoke Brush, part number 43078-99. 2.

INSTALLATION 1. Remove existing front wheel assembly. Save axle, axle nut, brake disc, and wheel spacers for kit installation. Refer to FRONT WHEEL in service manual. For FLSTC and FLSTN Models: Discard moon-style hub cap. or FXSTD: Discard tapered spacer. NOTE Install short valve stem (43157-83A) included in the installation kit. Discard all other valve stems. 2. See Figure 2. Install valve stem assembly (L) on wheel. Refer to TIRES in service manual. Do not re-use brake disc/rotor screws. Re-using these screws can result in torque loss and damage to brake components. (00319c) NOTES Install the primary bearing first using appropriate service manual and WHEEL BEARING REMOVER/INSTALLER. The side with the machined groove on the hub face is the primary bearing side for all kits except Kits 41681-07 and 40818-08. For Kit 41681-07: Install the wheel so that the hub markings are on the left side and the machined groove is on the right side of the motorcycle. • For 2006 and later FXDWG Models: When correctly installed, the tire will be 0.08-0.2 in (2-5 mm) off of center, compared to the fender. • For 2007 and later FX Softail and 2008 and later FXDWG Models: The left side of the wheel is the primary bearing side. • For 2006 and earlier FX Softail and 2007 and earlier FXDWG Models: The right side of the wheel is the primary bearing side. For Kit 40818-08: • Proper installation of this kit requires the separate purchase of two floating brake discs (44343-01 for 2004 – 2007 models and 44553-06A (stock) or 41500012 (polished) for 2008 and later models) and a tire (43371-07 on 2004-2008 models and 44026-09A on 2009-later models). The left side of the wheel has machined DOT markings to identify it as the primary bearing side. • For 2008 and later Touring: Install bearing shim (43903- 08) under the primary bearing. 3. Assemble wheel installation kit components and brake disc(s) to wheel, using the appropriate service parts table. Refer to FRONT WHEEL in service manual. 4. For FLSTC and FLSTN Models: Install wheel kit and right hand wheel spacer provided in installation kit. Refer to FRONT WHEEL in service manual.

The author of this manual has the conviction that the only way in which a meaningful and easy to follow text can be
written is first to do the work himself, under conditions similar to those found in the average household. As a result, the hands seen in the photographs are those of the author. Even the machines are not new: examples that have covered a consider- able mileage were selected so that the conditions encountered would be typical of those found by the average owner. Unless specially mentioned, and therefore considered essential, Honda service tools have not been used. There is
invariably some alternative means of slackening or removing some vital component when service tools are not available and
isk of damage has to be avoided at all costs. Each of the six Chapters is divided into numbered Sections. Within the Sections are numbered paragraphs. In consequence, cross reference throughout this manual is both straightforward
and logical. When a reference is made ‘See Section 5.12′ it means Section 5, paragraph 12 in the same Chapter. If another
Chapter were meant, the text would read ‘See Chapter 2, Section 5.12′. All photographs are captioned with a Section/paragraph number to which they refer and are always relevant to the Chapter text adjacent. Figure numbers (usually line illustrations) appear in numerical order, within a given Chapter. Fig. 1.1 therefore refers o the first figure in Chapter 1. Left-hand and right-hand descriptions of the machines and their component parts refer to the right and left of a given machine when the rider is seated normally. Motorcycle manufacturers continually make changes to specifications and recommendations, and these, when notified,mare incorporated into our manuals at the earliest opportunity.
We take great pride in the accuracy of information given in this manual, but motorcycle manufacturers make alterations and design changes during the production run of a particular n motorcycle of which they do not inform us. No liability can be ccepted by the authors or publishers for loss, damage or injury caused by any errors in, or omissions from, the information give
